Whenever Charles Logan is involved in something, automatically it is dirty. He has incriminating evidence on Novakovich and threatens to reveal it unless the Russians sign the treaty. I thought he would look for some quid pro quo from the Russians, but apparently he's actually looking for peace by any means necessary. That means shutting down Jack before he can extract all the information from Dana. Somehow, he is able to influence Taylor to join the dark side which isn't particularly a bad move. The writers paint the opaque situation in a transparent matter. Either Taylor preserves the peace or she upholds justice. There's no other option. The hard choice is made and Jack is the loser.
Jack stealing the helicopter...yeah, everyone saw it coming. Even Chloe was expecting it. The writers are going on the usual rogue --> hero path. It's yawn-worthy by now, but it occupied a small portion of the episode, so it wasn't enough to take away from the overall strength of the episode.
With the show turning to Jack flying around, I'm afraid this hour may be the last good episode before lots of inane yelling and moralizing which doesn't solve anything. Gregory Itzin brings it every time and had great chemistry with Cherry Jones, making for lots of solid scenes and a good episode.
Score: 8.8/10
